CVE-2023-49214
Official description Straight from the sourceThe vendor's or NVD's own wording, published unedited. Authoritative, but often terse — it says what broke, rarely what to do.
NVD · uneditedUsedesk before 1.7.57 allows chat template injection.
Technical summary Written by usOur analysis, written from the advisory, the CVSS vector and the affected-version data. It adds context the advisory leaves out, and never invents facts that are not in the source.
dbcve analysis · moderate confidenceUsedesk before version 1.7.57 is vulnerable to chat template injection, where malicious input in chat templates can be processed by the template engine without proper sanitization. This could allow attackers to inject arbitrary template code, potentially leading to cross-site scripting (XSS) or server-side code execution.

Am I affected? How to checkSteps we derive from the advisory and the affected-version data, so you can decide whether this CVE reaches your setup. They are a guide, not a scan — your own configuration is the authority.
dbcve checksWork through these to decide whether this CVE applies to you.
-
Determine your Usedesk versionAccess your Usedesk installation and locate the version information, typically found in the admin panel under system settings, about page, or by checking the software documentation for version lookup methods.Affected if The installed version is any version before 1.7.57 (for example, 1.7.50, 1.7.0, or 1.6.x)
-
Confirm chat templates feature is activeCheck whether your Usedesk instance has chat templates enabled or configured. Look for chat/template settings in the admin interface or configuration files related to the chat module.Affected if Chat templates are actively used or configured in your environment
-
Examine chat template configurations for user inputReview the chat template settings where administrators create or modify templates. Inspect template fields that accept dynamic input, such as placeholders for user names, messages, or custom content.Affected if Chat templates accept user-supplied data without visible sanitization or encoding controls
-
Test template rendering behaviorIf you have access to a test environment, create a chat template containing special characters or template syntax (such as {{, }}, <script>, or system command patterns) and observe how the system processes and displays this input.Affected if The template engine renders unsanitized input directly, displaying raw template syntax or executing injected code
You are affected if your Usedesk version is below 1.7.57 and chat templates that accept user input are in use, as the template engine will process malicious input without sanitization.

Remediation Closing itWhat it takes to close this. Where a vendor fix exists we point at it; where none exists we say so plainly, and can build one. Effort estimates are scoped from the advisory, not from your codebase.
dbcve · scoped1.7.57
Upgrade Usedesk to version 1.7.57 or later to obtain the patch. Additionally, implement input validation and output encoding for all user-supplied data in chat templates as a defense-in-depth measure.
1.7.57
- Obtain the latest Usedesk release version 1.7.57 or later from the official vendor (usedesk.ru)
- Review the upgrade documentation provided by Usedesk
- Backup the current Usedesk installation and database
- Deploy version 1.7.57 or later following vendor upgrade procedures
- Verify the chat template injection vulnerability is resolved by testing chat functionality
